Torque value of electric emergency shut-off valve
For example, the no-load torque value of Yonglong electric emergency shut-off valve and electric ball valve: for example, for PN40/DN50 caliber, the torque is 40Nm (Nm), plus 50% safety factor is 60Nm, and the pneumatic/electric actuator is 100Nm.
The actuators of "Yonglong Valve" emergency shut-off valve have the function of manual/electric automatic switching. The clutch free design can also rotate the hand wheel when the product is electrically operated without interference, so as to ensure the safety of the operator. This design mechanism will become the mainstream trend of the industry in the future.
The electric actuator adopts planetary gear technology to realize the combination of manual and electric control, and does not need a clutch mechanism to ensure the safety of operators. According to the different spindle of the valve, the output sleeve of the actuator is designed in the form of spline, and the inner hole can be replaced with square hole, keyway and other different sizes, which can be quickly debugged and replaced easily and quickly.
The bottom connecting hole of the electric emergency stop valve actuator is in accordance with the 1505211 standard, and there are a variety of connecting flanges of different sizes. It can be replaced and rotated on the same type of electric actuator to achieve the purpose of connecting with the valve flanges with different hole positions and angles.
The 360 ° angle indicator adopts a plastic 30 window indicator with high strength, sun aging resistance and Rs compliance. Users can clearly observe the travel position of the electric actuator within the 360 ° angle of view, without any dead angle.
